Product Overview
The CHEV82/NA is a versatile Fire Resistant (FR) marine communication cable that combines certified circuit integrity with effective electromagnetic shielding (EMS) and enhanced mechanical protection. Its construction features a mica/EPR insulated core for fire survival (IEC 60331), a PVC inner sheath, a flexible tinned copper wire braid serving as both armor and screen, and a final PVC outer sheath. This double-sheathed design is engineered for applications where fire resistance, protection against electromagnetic interference, and superior durability are required in demanding marine and industrial environments.
Key Features & Benefits
-
Fire Resistance with EMI Protection: Provides certified Fire Resistance (IEC 60331) for critical circuits, while the overall tinned copper wire braid armor offers excellent electromagnetic interference (EMI) shielding, protecting sensitive signals from noise in complex electrical environments.
-
Dual-Layer Sheath Protection: The PVC inner sheath acts as a bedding layer, and the robust PVC outer sheath provides comprehensive environmental, chemical, and abrasion resistance, ensuring long-term cable integrity even in harsh conditions.
-
Flexible & Durable Armor: Unlike rigid steel armor, the copper wire braid provides good flexibility for easier installation while still delivering reliable mechanical protection against wear, tear, and minor impacts.
-
Comprehensive Safety & Performance: Complies with key marine (IEC 60092) and fire safety standards, offering a balanced solution for circuits that require both operational reliability during a fire and signal clarity.

Applications
This shielded and armored fire-resistant cable is ideal for critical systems where signal integrity and circuit survival are both priorities:
-
Vital communication, navigation, and control systems on ships and offshore platforms that are sensitive to electrical noise and must remain functional in an emergency.
-
Instrumentation and data links in industrial facilities like power plants, chemical plants, and automation systems where EMI protection is necessary alongside mandatory fire circuit integrity.
